Decoration board for electric wire laid

ABSTRACT

A decoration board for concealing electric wires laid indoors, having a wire-laying board formed with partially formed wire-receiving grooves and an engaging board formed with partially formed wire-receiving grooves, the two boards secured together defining wire-receiving conduits. The decoration board is formed in sections which can be connected together by a board joint, inner angle board joint and external angle joint. The board joint may be provided with an opening for receiving an electrical receptacle.

BACKGROUND OF THE INVENTION

This invention relates to a decoration board, particularly a decorationboard used for concealing electric wires laid indoors. Today, in somerooms, electric wires are usually laid in a disordered manner, which notonly reduces the beautiful appearance of the room, but also can giverise to a fire hazard . Currently, a means has been developed to improvethat situation, i.e., a skirt board, in which a central groove isfurnished to house the wires; unfortunately, since all the wires arelaid in one groove, the possibility of fire hazard still exists. If onewire is set on fire as a result of a short-circuit, the other wires willalso be set on fire. In other words, the possibility of a fire hazardwill surely be increased.

SUMMARY OF THE INVENTION

In view of the aforesaid facts, the inventor has developed a decorationboard for electric wires laid indoors, which board not only solves thesafety problem, but also fulfils the beautiful appearance requirement ina room. The feature of the present invention is to use two pieces ofengaging boards to form a number of pipe-shaped cylinders, in whichwires may be laid respectively for safety purpose. The outer surface ofthe board is formed into a saw-tooth shape, which tucks away thefastening nails, and also presents an elegant appearance in the room.

DETAILED DESCRIPTION

FIG. 1 illustrates an exploded and perspective view of the presentinvention. FIG. 3 illustrates a sectional view of the wire-laying boardand an engaging board assembled together. At top and bottom of awire-laying board 1, there is a flange 10 respectively; between that twoflanges, there are furnished a number of spaced wire-laying channels 11.At top and bottom of a saw-tooth-shaped engaging board 2, there isfurnished a soft sealing strip 20, of which the top one is bentinwardly, while the bottom one is bent outwardly. The Horizontalsaw-tooth-shaped strips 20a between the two soft sealing strips 20 eachhave a perpendicular side 20b to the engaging board 2 and a parallelside 20c to the engaging board 2 so as to form a tucked nail groove 21.At the top and bottom and on the back side of the engaging board 2, anengaging flange 22 is furnished respectively so as to fit with theengaging flange 10 of the wire-laying board 1. The upper engagingflanges 22 of the engaging board 2 are slightly bent upwardly and thelower flanges 22 are slightly bent downwardly. A round channel 23 on theengaging board 2 has an open portion at its upper left corner. As shownin FIG. 1, between the teeth on the front of the board joint 3, thereare furnished tucked nail grooves 31. Grooves 31a on the rear of theboard joint 3 are used as wire channels 32. An internal angle boardjoint 4 includes a saw-tooth-shaped front board and a rear board beingmoulded in one piece from the top end; the grooves between the teeth onthe front board are used as a tucked nail groove 41, while the groovesbetween the teeth one the rear board are used as wire channels 42.Further, an external angle board joint 5 includes a saw-tooth-shapedfront board and a board being moulded in one piece from the top end;grooves between the teeth on the front board are used as tucked nailgrooves 51, while grooves between the teeth on the rear board are usedas wire channels 52. A receptacle installing board 6 is made of twopieces of saw-tooth-shaped boards being moulded in one piece from thetop end; a slot in the central portion of the front and rear boards ofthe receptacle installing board 6 is used as the receptacle hole 61.Between two teeth on the front board of the receptacle installing board6, there are furnished tucked nail grooves 62; the grooves on the rearboard define wire channels 63.

FIG. 2 is a perspective view of the present invention, as assembled.Upon installing the present invention along a wall, the wire-layingboard 1 is secured with an adhesive or nail to a wall surface first, andthen wires 7 are placed in the wirelaying channels 23; then, theengaging board 2 is placed over the wire-laying board 11 wire-layingchannel 11 and the covering channel 23 are assembled together to forminto a cylinder to lay a wire 7. Simultaneously, the engaging flange 10of the wire-laying board 1 and the engaging flange 22 of the engagingboard 2 will be engaged with each other so as to attach the engagingboard 2 to the wire-laying board 1. In order to have the engaging board2 firmly attached to the wire-laying board 1, a number of screws 8 maybe used to fix the engaging board 2 to the wire-laying board 1 along thetucked nail grooves 21 at a suitable height. In case oftrouble-shooting, just remove the screws 8 and the engaging board 2. Thetop and bottom soft sealing strips 20 on the engaging board 2 willclosely attach to the wall and floor respectively.

Referring to FIG. 4, there is a sectional view showing the way ofengagements between the engaging board 2 and the board joint 3. For thejoint on a flat surface, the board joint 3 may be used to cover the twoends, which are a little longer than those of the wire-laying boards, oftwo engaging boards 2; in that case, the wire 7 will be inserted intothe wire channel 32 on the rear board of the board joint 3. In case of ajoint being an internal angle of wall, FIG. 1, an internal angle boardjoint 4 may be used to cover the two ends, which are a little longerthan those of the wire-laying boards 1, of the two engaging boards 2;the wire 7 will be inserted into the wire channel 42 on the back side ofthe rear board of the internal angle board joint 4. In case of a jointbeing an external angle of wall, FIG. 1, an external angle board joint 5may be used to cover the two ends, which are a little longer than thoseof the wire-laying boards 1, of the two engaging boards 2; the wire 7will be inserted into the wire channel 52 on the back side of the rearboard of the external angle board joint 5. In case of a joint beingalong a flat wall surface, a receptacle 9 will be installed in thereceptacle hole 61 on the receptacle installing board 6, while the wire7 will be inserted into the wire channel 63 on the back side of the rearboard of the receptacle installing board 6. In that case, both ends ofthe receptacle installing board 6 will cover the two ends, which are alittle longer than those of the wire-laying boards 1, of the twoengaging boards 2.

In the present invention, a round conduit formed by the wire-layinground channel 11 and the covering channel 23 is used for laying thewire. Moreover, in case of one wire having a short-circuit, the restadjacent wires would not be affected because of the spaced round wirechannels providing additional protection for each wire in the boards.The nail grooves 21 on various levels on the engaging board 2 can tuckedaway the screws from view, i.e. increasing the beauty of the board.Since the upper and the lower soft sealing strips 20 of the engagingboard 2 can closely be attached to the wall surface and the floorsurface respectively, no water and dust will enter into the area coveredby the present invention.
